Abstract
Provided are a data transmission method and apparatus. The method includes that a first node configures configuration information of each time unit within a transmission period, where the configuration information includes a transmission direction and transmission content in each time unit, that the first node notifies the configuration information to a second node, and that the first node performs data transceiving with the second node according to the configuration information.
Claims17
A data transmission method, comprising:
- configuring configuration information of each time unit within a transmission period, wherein the configuration information comprises:
- a slot structure of each time unit;
- notifying the configuration information to a second node;
- and
- performing data transceiving between a first node and the second node according to the configuration information;
- wherein configuring configuration information of each time unit within a transmission period comprises:
- determining the transmission period;
- configuring a transmission resource for uplink transmission within the transmission period, and configuring a transmission resource for downlink transmission within the transmission period;
- and
- configuring the slot structure within the transmission period, wherein the slot structure comprises at least one of:
- an uplink slot structure or a downlink slot structure;
- wherein configuring the slot structure within the transmission period and notifying the configuration information to a second node comprise one of:
- semi-persistently configuring the slot structure of each time unit or a potential slot structure of each time unit, and indicating, through dynamic downlink control information, ‘DCI’, the slot structure of a time unit to be adjusted;
- configuring a structure of a remaining flexible-resource part of each slot within the transmission period, and notifying the structure of the remaining flexible-resource through the DCI, wherein the structure of the remaining flexible-resource indicates at least the slot structure of the remaining resource part of each slot within the transmission period;
- notifying, through a group common physical downlink control channel or a common physical downlink control channel, the slot structure of each time unit within the transmission period, and notifying, through UE-specific downlink control information, the second node of a time unit whose slot structure is changed;
- notifying, in a license assisted access manner, the structures of a current time unit and one or more time units next to the current time unit, wherein the structures at least indicate the slot structures of respective time units;
- determining and notifying, through semi-persistent configuration or predefinition, that a first symbol or first two symbols of each time unit is or are used for downlink transmission, and a last symbol or last two symbols of each time unit is or are used for uplink transmission;
- or
- semi-persistently configuring a candidate time-unit structure, wherein the candidate time-unit structure indicates at least the slot structure of a time unit;
- wherein the group common physical downlink control channel carries indication information for indicating a resource discarded for ultra reliable and low latency communication traffic.

A data transmission method, comprising:
- receiving configuration information configured by a first node, wherein the configuration information comprises a slot structure;
- and
- performing data transceiving between a second node and the first node according to the configuration information;
- performing data transceiving between a second node and the first node according to the configuration information comprises:
- when information configured semi-persistently and information configured dynamically conflict, determining, by the second node, the transmission direction and the transmission content according to latest received dynamic downlink control information signaling or configured priority of information to be transmitted;
- wherein determining, by the second node, the transmission direction and the transmission content according to the latest received dynamic downlink control information signaling or configured priority of the information to be transmitted comprises one of:
- transmitting, by a scheduled second node, data according to a latest scheduling signaling or slot format, and punching, according to signaling configured semi-persistently, at a transmission position of a reference signal in different direction to discard data in uplink transmission or downlink transmission at the punched position;
- indicating dynamic adjustment of a transmission position of an aperiodic reference signal, wherein for the scheduled second node, performing indication through UE-specific downlink control information, and for a non-scheduled second node, performing indication through a group common physical downlink control channel;
- for data transmission of a semi-persistent scheduled and grant-free second node, adopting downlink control information again to schedule a new resource, or indicating an ending of current transmission;
- and for a zero power-channel state information-reference signal, reserving transmission data;
- when unicast downlink control information indication of the second node is not received or transmission direction information is not indicated in the unicast downlink control information, determining the transmission direction and the transmission content according to the group common physical downlink control channel;
- priority of a semi-persistently configured ensured fixed resource being higher than priority of a resource notified through downlink control information;
- or
- determining the transmission direction and the transmission content according to pre-configured information or specific downlink control information;
- wherein the group common physical downlink control channel carries indication information for indicating a resource discarded for ultra reliable and low latency communication traffic.
